Module: Nortel-Magellan-Passport-LogicalProcessorMIB
OID (symbolic): Nortel-Magellan-Passport-LogicalProcessorMIB::lpSdhUnusableTxClockRefAlarm
OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.15.16.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description:
This attribute displays whether an Unusable Transmit Clock Reference (UTCR) alarm state has been entered. A UTCR alarm state is entered when a Sonet/Sdh port provisioned to act as a transmit clock reference has received the code 'do not use for synchronization' in the S1 byte (in the SONET/ SDH line overhead) for 2.5 +/- 0.5 seconds. The condition is cleared after not detecting the 'do not use for synchronization' code for a period of 10 +/- 0.5 seconds or when the port is no longer provisioned to act as a transmit clock reference. A port is acting as a transmit clock reference if it is provisioned with a) a clockingSource of line, or b) it has been provisioned as a primaryReference, secondaryReference or tertiaryReference in the NetworkSynchronization component. The unusableTxClockRefAlarm attribute is always set to off when the component has been locked and left offline.
